Dont know why everyone is steering clear of this question?
I dont know a whole lot about triggers but I can tell you that I bought I trigger kit for an AR and it fit my 15-22 nicely.
So, Im guessing that if you wanted to just replace the hammer it self,then yes it would fit.

I don't know if the basic 15-22 has a mil-spec hammer dimensionally but the entire trigger group can be swapped out for any AR trigger than uses a .154" trigger pin size. If you want it really locked down and also to reduce wear you can mount the trigger with a set of AR15-22 special KNS non-rotating trigger pins. I think the 15-22 pins, which are longer because the S&W receiver is thicker than a stock AR, are only available in the KNS Gen 2 Mod 2 pin version..

I put a Timney in mine and had to use anti-walk pins because the set screws on the trigger group were flexing the poly. I used a set of JP anti-walks from a standard AR and they worked just fine. Won't catch as many threads, but works fine. About 4k through it and no issues.

You can install ANY AR-15 FCG in the 15-22.

If you are installing the Timney only use the 4.5lb spring as the 3 or 4 may result in light strikes, also ask for the plate for composite lowers, it is a thin steel plate that goes under the trigger.

I went with the 3 lb for the slidefire, got lucky as I haven't had any light strikes, but that's good info. I really wish I would've been told about the plate as well, I almost muffed up my lower pretty bad. The screws didn't seem like they were getting that tight, and the trigger was still moving around so I was going a little tighter when I accidentally dropped my tiny Allen wrench. Good thing, because I set my gun down, reached down and grabbed the wrench, and when I was standing back up I noticed this...

I have an S3G in one and an RRA NM in the other. you can also drop in modular triggers like the Timney, CNC, and, Wilson Combat. I also installed the special 15-22 version of the KNS non-rotating locking trigger pins.

I did the same. You need to take it out and install some metal shims under the set screws.

I just backed them out and went with the anti-walk pins, easier to remove in my opinion as well. I had a hell of a time moving the spring leg out of the way to get my Allen down to the set screw. Since I went to the anti-walks, I just won't be touching those evil little set screws anymore
where can I gt these pins ?I have a enhanced spikes trigger that I could put in it.

I installed a their SSA about a month ago, but sadly haven't had a chance to shoot it yet. Sure feels better than the stock trigger in crispness, and only slighter in pull weight.

You will need the longer KNS pins that are made specially for the 15-22. Check with Primary Arms, they seem to have the best prices.

I don't know about everyone else, but I got a set that came with a JP trigger and they worked just fine. It was a sealed package and the packaging didn't say anything about 15-22. I'm guessing they weren't the 15-22 KNS ones, but still work fine. They dont catch as many threads, but haven't came loose over a few thousand rds.
